[ETO_Alpha] TX Relay Problem-91B

[George & Marijke Guerin]

HELP!
    Sunday while ragchewing, one of the relays in my Alpha 91B decided to
not go to RX position.  Here are the simptoms:
1.    It is such that with the Alpha off, I can run the transceiver through
the amplifier.
2.    With the amplifier on, either in Standby or Operate positions, one of
the internal relays is activated to TX position.  Then I can hear only using
the RX antenna jack which has a beverage antenna selector attached.  One
cannot run "barefoot" with the amplifier on.
3.    With the amplifier on, I can transmit through the amplifier, if I use
the RX antenna jack for receiveing on a separate antenna.
    My first guess is that a component on a relay circuit has failed and is
pulling one of the relays to ground.  I have not opened up the box (yet) but
will do so today.
    All thoughts will be appreciated.
